945819 divided by 80 
Our goal is to divide 945819 by 80.

Step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 80

Moving on to step 2:
80 can be fit into 94 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 80 away from 94, we end up with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 80

Step 3:
80 can be fit into 145 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 80 from 145 to get 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 80

Moving on to step 4:
When dividing 658 by 80, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 640 from 658 and we're left with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 80

Moving on to step 5:
80 goes into 181 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 1182.0
If we take 160 away from 181, we end up with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 80

Step 6:
If we divide 219 by 80, we get 2 and a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 11822.0
Deduct 160 from 219 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
When dividing 590 by 80, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 11822.7
Deduct 560 from 590 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 80 is 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 11822.73
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 11822.737
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11822.7375
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11822.7375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11822.7375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 11822.7375 and a remainder of 0.0.
